Formal Logic

ClaudeCommunityby Reasoning.services

Formal Logic MCP is a Model Context Protocol server that provides deterministic reasoning capabilities without any LLM dependencies. It offers: * **Propositional Logic**: SAT solving, CNF conversion, consistency checking, and entailment. * **First-Order Logic**: Theorem proving using the Z3 SMT solver. * **Temporal Logic**: Trace-based LTL model checking. * **100% Deterministic**: Identical input always produces identical output — fully cacheable and auditable. * **High Performance**: Fast execution taking under 5 seconds for typical queries. Ideal for API contract verification, state machine validation, detecting contradictions in business rules, and system requirements analysis.
